Re: which linux?
It's always a good idea to pick a distribution you know you can get personal support with. If you know someone who's familiar with Linux and who is willing to help, it's a safe bet to start with the distro he uses. Quite obvious, but sometimes people don't realize this.
Christianity, noun: The belief that a cosmic Jewish Zombie who was his own father can make you live forever if you symbolically eat his flesh and telepathically tell him you accept him as your master, so he can remove an evil force from your soul that is present in humanity because a rib-woman was convinced by a talking snake to eat from a magical tree.
